AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
Declare it as business income, converted to Australian dollars. The ATO says Australian residents must declare foreign income, that consultancy and business fees from overseas clients are declared as if earned in Australia, and that all foreign amounts must be converted using its translation rules or an average rate from its published rates. Nigerian tax withheld is not deducted from income; it may support a foreign income tax offset only if you paid it, can prove it, and Nigeria had the right to tax.
Fees from Lagos or Abuja clients go on your Australian return in the same way as fees from Brisbane clients, with three extra steps: conversion into AUD, a decision on any Nigerian tax withheld, and a careful split of years where needed. This article follows the ATO's own pages; it is information, not tax advice.
Step 1: check your residency
Everything below assumes you are an Australian resident for tax purposes. The ATO's page on foreign and temporary resident income (last updated 8 June 2026) says temporary residents generally do not pay Australian tax on most foreign income, but may still be taxed on income from employment or services performed overseas while a temporary resident, and that foreign residents generally do not declare income from outside Australia. If you hold a temporary visa, settle this first, ideally with a registered tax agent; it changes the whole answer.
Step 2: declare the fees as business income
The ATO's page for Australian residents (last updated 15 June 2026) says that if you earn business income or consultancy fees from overseas, including through overseas platforms, "you need to declare relevant income as if it were earned in Australia". For a sole trader that means the business section of the individual return with the business schedule, alongside fees from Australian clients. The ATO page does not name return labels; your tax software or agent maps them.
Step 3: convert every amount to AUD
"You must convert all foreign income, deductions and tax offsets to Australian dollars in your tax return," the ATO says. You may use the exchange rate in effect at the times set by its translation (conversion) rules, or an average rate based on the daily and monthly rates it publishes monthly. Choose a method and apply it consistently, to expenses paid in naira as well as fees received.
| Item | What to convert | Where the rate comes from |
|---|---|---|
| Fee received in naira | Gross invoice amount | ATO translation rules or ATO average rate |
| Fee received in USD | Gross invoice amount | Same methods |
| Nigerian WHT deducted | Tax amount on the receipt | Same methods, if you claim an offset |
| Expenses paid in naira | Each deductible expense | Same methods |
Most countries do not use a 30 June year end, the ATO notes, so foreign income and offsets may have to be split across more than one Australian return. A WHT receipt dated December and one dated the following January can fall into the same Australian year, so date each one.
Step 4: deal with Nigerian tax withheld
Nigerian companies often deduct withholding tax from non-residents' fees; PwC's summary of the 2024 regulations gives 10% for professional, consultancy, technical and management fees. Declare the gross fee. The ATO says a foreign income tax offset needs tax actually paid overseas, records proving it, and a foreign country with taxing rights; if the country had no right, you can ask it for a refund. Over $1,000, you first work out your offset limit using the ATO's FITO rules guide. Because Nigerian guidance conflicts on whether work done outside Nigeria is taxable there, read Nigerian withholding tax on your fees before claiming.
Worked example
Example only, rates invented. Tunde, a resident designer in Sydney, earns ₦4,000,000 from two Nigerian clients in a year. At the average rate he applies, 1 AUD = ₦1,000, that is A$4,000 of business income. One client withheld ₦200,000 (A$200 at the same rate) and gave him a receipt. He declares A$4,000, deducts his business expenses as usual, and his agent considers whether the A$200 supports an offset.
Common mistakes
- Declaring only the net amount that arrived after Nigerian tax was deducted, instead of the gross fee.
- Mixing methods: converting some receipts at the day's rate and others at an average, without a reason.
- Leaving out naira income because it never left Nigeria. For a resident, income held abroad is still income.
- Forgetting deductible expenses paid in naira, such as a Lagos co-working desk used on a work trip, if they relate to earning the income.
- Treating a later loss on converting naira as a reduction in fee income, rather than asking how the currency movement should be reported.
If you find a mistake in an earlier return, the ATO lets you amend it; ask your agent about the time limits that apply to your situation.
Step 5: records
- Contracts and invoices, with dates and currencies.
- Bank or account statements showing each receipt.
- The exchange-rate method used and the rate for each amount.
- Nigerian WHT receipts.
- Expense receipts, including those paid in naira.

Where Pryme fits
A Pryme Business Account keeps naira and dollar receipts in their own currencies with a dated history, and the Finance agent can prepare a year-end list of receipts by currency for you or your agent to check. It prepares; you approve. Statements can be issued as verifiable documents through VerifyDoc.ai.
Questions people ask
Do I have to declare income from Nigerian clients in Australia?
If you are an Australian tax resident, yes: the ATO says residents must declare foreign income, and overseas business income is declared as if earned in Australia.
Which exchange rate does the ATO accept?
The rate set by its translation rules for the relevant time, or an average rate based on the rates the ATO publishes monthly.
Can I deduct the Nigerian tax as an expense?
The ATO treats foreign tax through the foreign income tax offset, which needs proof of tax paid and that the foreign country had taxing rights. Declare the gross fee.
What if I am on a temporary visa?
The ATO says temporary residents generally do not pay tax on most foreign income, with an exception for income from work or services. Get advice on your facts.
